Monitoring Three Plasmopara halstedii Resistance Genes in Iranian Sunflower Inbred Lines
Background: Downy mildew caused by Plasmopara halstedii is one of the most devastating diseases of sunflower worldwide. So far several dominant resistance genes designated as Pl have been identified and their molecular markers linked to these genes are available. However, no information on the resistance genes is available in Iranian lines. Objective: In this study, the presence of three map-b...
متن کاملConcentation of Mineral Elements in Callus Tissue Culture of Some Sunflower Inbred Lines
Concentration of mineral elements in calli of six sunflower inbred lines have been determined. Calli were induced from cotyledons of seven days old seedlings grown under sterile conditions. The differences between inbred lines in concentration of N, P, K, Mg, Fe and Mn were significant, whereas differences in the concentration of Ca, Na, Cu and Zn were insignificant. Average concentrations of m...
متن کاملThe influence of morphological differences between sunflower inbred lines on their SCA effects for yield components.
Genetic distances between seven oil sunflower inbred lines expressed in the variability of five morphological traits were analysed in terms of their effect on the specific combining ability (SCA) effects in these lines for yield component traits. The multivariate analysis of variance (MANOVA) and other related multidimensional methods were used to recognize the differences between genotypes wit...
متن کاملCytomorphological and molecular diversity in backcross-derived inbred lines of sunflower (Helianthus annuus L.).
A set of 250 distinct, stable, and uniform backcross-derived inbred lines were developed in sunflower through 5 interspecific cross combinations involving 4 wild diploid annual species (Helianthus argophyllus, H. petiolaris, H. annuus, and H. debilis). The presence of the wild-species genome in these inbred lines was confirmed through higher chromosome associations (tri- and quadrivalents) at d...
متن کاملResponse of Iranian Rice Recombinant Inbred Lines (Oryza sativa L.) to Salt Stress in Seedling Stage
Study of the morphological genetic diversity of 114 lines, which have been derived from the crosses between Tarom Mahalli and Khazar cultivars, has been performed at seedling stage as completely randomized design at the normal condition and salinity stress of 8 dS.m-1 in a hydroponic system. Significant differences were detected between genotypes for all traits. Mean of comparison demonstrated ...
